4. As the tines begin to make contact with
the ground, hold back on the handles so
that the tines will dig into the soiI and not
ride forward over the ground.
5. Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water'. Also, tilling soil that is too wet
will be hard on the machine and produce
unsatisfactory clods.
6. Lowering the depth stake will slow the
cultivator and make it till deeper'. Raising
the depth stake will allow it to move fast-
er and till more shallow. See "How To
Set The Depth".
_ ARNING: Keep away from the

OPERATION
BEFORE STARTING THE ENGINE
How To Prepare The Engine
A WARNING: Always use a safety
fuel container. Do not smoke
_when adding the fuel mixture to
the engine. When inside an enclosure,
do not fill the fuel tank. Before you add
the fuel mixture, stop the engine. Let the
engine cool for several minutes.
How To Mix The Fuel Mixture
The two cycle engine, used on this cultivator,
requires a mixture of gasoline and oil for lu-
brication of the bearings and other moving
parts. The correct fuel mixture ratio is 24:1
(5.2 oz. oil per one gallon of gas - see the
Fuel Mixture Chart). Gasoline and oil must
be pre-mixed in a clean gasoline container.
Always use fresh, clean, unleaded gasoline.
Mix gasoline and oil as follows:
1. Pour one (1) U.S. quart of fresh, clean,
unleaded automotive gasoline into a one
gallon size gasoline container.
2. Add 5.3 ounces of clean, high quality,
two-cycle oil to the gasoline container.
3.
4.
5.
IMPORTANT: Do not use outboard mo-
tor oil or multi-viscosity oils,such as
10W-30 or 10W-40.
install the fuel cap onto the gasoline con-
tainer. Vigorously shake the gasoline
container to mix the oil with the gasoline.
Add an additional three (3) U.S. quarts of
gasoline to the gallon container. Again
shake the gasoline container.
This completes the gasoline mixing pro-
cedure. The gasoline can now be added
to the fuel tank.

OPERATION
CULTIVATING TIPS
Tilling is digging in, turning over and
breaking up packed soil before planting.
Loose unpacked soil helps root growth.
Best tilling depth is 4 to 6 inches. A tiller
wiII also clear the soil of unwanted vege-
tation. The decomposition of this vegeta-
tion matter enriches the soil. Depending
on the climate (rainfall and wind), it may
be advisable to tilI the soil at the end of
the growing season to further condition
the soil.
Avoid tilling soil that is too dry as it will
pulverize and produce a dust that will not
hold water. Also, tilling soil that is too wet
will be hard on the machine and produce
unsatisfactory clods.
If the cultivator stops forward motion and
tries to dig deeper than necessary, move
the handles from side to side to start for-
ward motion.
Cultivating is loosening or digging
around growing plants which allows the
plants to flourish.
When using the cultivator to remove
weeds, it is best to cultivate no deeper
than 1-1/2 inches. Cultivating deeper will
only pull to the surface ungerminated
weed seeds. Raising the depth stake wilI
allow it to move faster and till more shal-
low.
Better growth will be obtained if an area
is tilled properly and used soon after till-
ing to preserve the moisture content.
When cultivating around piants or close
areas, you may want to remove the out-
side tines. See "Tine Replacement" in
the Service/Adjustments section.
The depth stake (on the back of the culti-
vato o serves a dual purpose. It helps
regulate the depth of the cut and also
acts as a brake to help the operator con-
trol the speed of the cultivator.
Lowering the depth stake will slow the
cultivator and make it till deeper'. Raising
the depth stake will allow it to move fast-
er and till more shallow.
WARNING: Read the Owner's
manual. Know location and
functions of all controls. Keep
all safety devices and shields in place.
Never allow children or uninstructed
adults to operate cultivator. Shut off en-
gine before unclogging tines or making
repairs. Keep bystanders away from ma-
chine. Keep away from rotating parts
and tines. They can cause injury.

HOW TO ADJUST THE CARBURETOR
A dirty air cleaner will cause the engine to
run improperly or to smoke excessively. Be-
fore adjusting the carburetor, make sure the
air cleaner is dean. Never make unneces-
sary adjustments to the carburetor'. The car-
buretor was set at the factory to operate
efficiently under most applications. However,
if adjustments are required, we recommend
you contact your nearest Sears Service Cen-
ter. If you feel that you are competent to
make carburetor adjustment proceed as foI-
lows.
_lb WARNING: Use extreme care
when making adjustments that
require the engine to be run-
ning. Keep hands, feet, hair and loose
clothing away from all moving parts.
1. Turn the mixture adjustment screw
clockwise to until closed (see Figure 12).
IMPORTANT: To prevent damage to
the carburetor or to the adjusting
screw, tighten the adjustment screws
with your fingers.
2. Turn the mixture adjustment screw
counterclockwise one turn.
3. Start the engine and let it warm up for
approximately 3 to 5 minutes. Do not ad-
just the carburetor when the engine is
cold.
4. If the engine runs erratically or stops af-
ter the choke lever is moved to the
CHOKE OFF position, then open the
mixture adjustment screw an addition-
al 1/8 turn counterclockwise.
5. With the engine running, release the
throttle control (idle position) to make the
mixture adjustments.
6. Slowly turn the mixture adjustment
screw clockwise until the engine begins
to run erratically. Note this position.
7. Then, slowly turn the mixture adjustment
screw countercIockwise until the engine
again begins to run erraticaliy. Note this
position.

_lb ARNING: Never store the cul-
tivator indoors with fuel in the
fuel tank. Never store in an en-
closed, poorly ventilated area where
fumes could reach an open flame, a
spark or a pilot light as on a furnace, wa-
ter heater or clothes dryer.
_lb ARNING: Do not remove gas-
oline while inside a building,
near a fire, or while you smoke.
Gasoline fumes can cause an explosion
or a fire.
Cover the cultivator with a suitable pro-
tective cover that does not retain mois-
ture. Do not use plastic.
IMPORTANT: Never cover the cultivator
while the engine and exhaust areas are
still warm.
NOTE: A yearly checkup or tune-up by a
Sears Service Center is a good way to
make sure that your cultivator will pro-
vide maximum performance for the next
season.
When the cultivator is put in storage for thirty
days or more, follow the steps below to
make sure the cultivator is in good condition
the following season.
Cultivator
Completely dean the cultivator.
Remove the tines. Clean and apply oil to
the tine shafts. Mount the tines onto the
tine shafts. See "How To Remove And
Install The Tines" in the Service And Ad-
justments section.
Loosen the knobs that secure the upper
handle to the lower handle. Carefully fold
the upper handle. Make sure the throttle
cable is not bent. Tighten the knobs.
The cross piece of the upper handle (be-
tween the lower handles) can now be
used as a carry handle. To store the cul-
tivator up off the floor and out of the way,
the cross piece can also be hooked over
a wall hook.
Put the cultivator in a building that has
good ventilation.
Engine
IMPORTANT: It is important to prevent
gum deposits from forming in fuel system
parts such as the carburetor, fuel filter,
fuel hose, and tank during storage. Also,
using alcohol-blended fuels (called gaso-
hol, ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an en-
gine while in storage.
To prevent engine damage when the cultiva-
tor is in storage for 30 days or more, follow
the steps below:
Let the engine rununtil it is out of gaso-
line.
Slowly pull the starter handle until you
feel resistance due to compression in
the cylinder, then stop.
Slowly release the starter rope. This
position will close both the intake and the
exhaust ports and help prevent corrosion
of the piston and cylinder.
